Why this rock is probably not a meteorite:

1) No fusion crust (top photo).

2) Shape is not aerodynamic (top photo).

3) It looks like it might be layered (top photo).  Meteorites aren't layered.

4) A broken surface (bottom photo) looks like a sandstone - quartz sand (gray) grains cemented with iron oxide (reddish). The maximum dimension of the rock chip in the photo is 3.5 cm.
What is it?

Almost certainly, this is a terrestrial quartz sandstone, a rock type that is very common on earth but which does not occur among meteorites.  The finder thought that the rock looked like lunar meteorite QUE 94281.
